Key Estimator™ Spreadsheet

The KeyEstimator spreadsheet (MS Excel) allows the user to quickly estimate the square feet of wall and caps, soil reinforcement, draining fill, reinforced fill and base leveling pad material that you would need to build a wall.

NOTE: The KeyEstimator Tool from Keystone is not intended to perform engineering design or analysis functions as those tasks are beyond the scope of a simple spreadsheet. Please refer to the Keystone Design Manual and KeyWallPRO Design Software for the more rigorous considerations of retaining wall design. The responsibility for good engineering judgment, architectural considerations, and construction experience is the responsibility of professionals specializing in such work. Keystone accepts no responsibility for the improper use of this spreadsheet.
